Examined drug preferences of a group of active multiple drug abusers referred for treatment. Nearly half the respondents preferred drugs other than type they most frequently used. Preferences were related to method of administration. Results suggest preference is one among several determinants of drug use. (Author/BEF)

A random sample of university students was interviewed concerning illicit psychotropic drug use and administered the Personality Research Form. Univariate and multivariate analyses strongly supported the hypothesis that nonusers, moderate users, and heavy users of illicit drugs differ in personality characteristics. (Author)

Students completed California Psychological Inventory, Adjective Check List, and drug-use questionnaire. Continuous nonusers never disclosed marijuana use. Switched nonusers did not disclose marijuana use initially but did so later. Users disclosed marijuana use initially and later. Marijuana use can be predicted by patterns of reported…

Examined interrelationships among sex, race, drug-use patterns, and personality variables in chronic users of illicit drugs. Blacks were characterized by lower levels of sensation seeking, less psychopathology, use of fewer drug categories, and later drug use than Whites. Use and personality patterns among women differed little from men.…

The purpose of the present study, is to determine to what extent Change Seeker Index scores correlate with the reported incidence of specific behaviors judged by the authors to rank high in stimulation-seeking characteristics. (Author)

Drug abuse scores from prisoners resulted in two factors describing lifetime use of cannabis versus opiates. Analysis of Minnesota Multiphasic Personality Inventory (MMPI) profiles versus drug abuse patterns indicated moderate, unidimensional relationship between variables. MMPI profiles of opiate users were similar to those identified in research…

Polydrug (non-opiate-drug) abusers have previously been classified by a variety of typologies that can be characterized as either descriptive, functional, or a combination of both. This investigation proposes two objective scoring systems that classify polydrug users on a streetwise/straight dimension and on a self-medication/recreational-use…

Examined subgroups of people in relation to specific types of drugs. Multiple drug clusters identified here yielded six basic drug clusters. Typology of drug abusers was developed by proximity cluster analysis. Set of psychosocial measures was differentially related to use of types of drugs and drug abusers. (Author/BEF)

MMPI was given to 145 male and female drug abusers on admission to three therapeutic communities, and retests were done at the finish of the first phase of the program. Comparisons of stayers and quitters showed quitters higher on the F and psychotic scales. (Author)

The Sensation-Seeking Scale and The State-Trait Anxiety Inventory were administered to 30 white, 30 black, and 30 Hispanic male narcotic drug abusers. White subjects scored significantly higher on the five Sensation-Seeking subscales. No significant differences were obtained between ethnic groups on state or trait anxiety. (Author)

Investigated the empirical derivation of clinically and theoretically meaningful subtypes among males arrested for driving while intoxicated. Five subtypes were defined through cluster analysis of driving--attitudinal, personality, and hostility measures. Two subtypes were found to have particularly high levels of risk-enhancing traits.

Compared self-concept scores from the Tennessee Self Concept Scale of alcohol- and drug-dependent men. Analysis yielded three significant results: true-false ratio, psychosis, and personality disorder. Data indicated similarity in all men regarding self-concept. A multivariate design in examining substance patterns and self-concept was…

An anonymous survey of adolescents (N=3,690) was used to assess how much of the unique variance in adolescents' self-reported drug use was accounted for by number of parents in comparison to the adolescents' sex, age, social class, and peer drug use. (Author)
